Effect of antianginal drugs in stable angina on predicted mortality risk after surviving a myocardial infarction: a preliminary study (METRO).

Background Although antianginal drugs are used over several months and through to years in stable angina, there is scant evidence regarding their influence on outcomes. The METRO (ManagEment of angina: a reTRospective cOhort) study sought to assess the independent effect of using these drugs on subsequent mortality risk in patients with stable angina.
